Multiband Switchable Microwave Absorbing Metamaterials Based on Reconfigurable Kirigami–Origami
A reconfigurable metamaterial featuring tunable microwave‐absorbing and load‐bearing performance is proposed. Stretchable kirigami and bistable origami configurations are integrated as actuating components, and the synergistic deformation mechanisms are systematically analyzed.

DAILY VARIATION IN EARTH'S MAGNETIC FIELD
Daily variation in Earth's magnetic field is changed during the time of the day and according to Earth's latitude and lengthwise. Due to great sensitivity of new proton magnetometers there is a question how daily variation vary according to distance from

The study of the Earth's magnetic field is one of the oldest scientific disciplines. Research in geomagnetism enabled information to be deduced about the Earth's interior, the electrodynamics of the upper atmosphere at altitudes above 100 km, and the processes at work in interplanetary space and even on the surface of the Sun.Regular recordings of the ...

GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...

Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres
MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...

Magnetic declination of the territory of Ukraine: the results of observations and calculations
A technology is proposed for calculating the strength and angular components of the vector of the induction of the Earth's magnetic field. The technology is based on the development of a three-dimensional model of the earth's crust and the calculation of
